@syedsadiqali did you find any solution?

[hashimkhatri]

I find a jack its not a proper solution:
some changes in this file (node_modules@react-native-community\cli-platform-android\native_modules.gradle)

in this variable ----> def generatedFileContentsTemplate (line no 8) you gonna see this {{ packageImports }} (line no 21) after this add import fr.michaelvilleneuve.customcrop.RNCustomCropPackage;

and

in this function ----> void generatePackagesFile(File outputDir, String generatedFileName, String generatedFileContentsTemplate) { (line no 121) replace this line ---->
"// ${it.name}\n${it.packageImportPath}"
with
if(it.name != "react-native-perspective-image-cropper"){
"// ${it.name}\n${it.packageImportPath}"
}else{
"// ${it.name}\n //${it.packageImportPath}"
}

Same issue here, not sure how to fix it

Hi,

the package is not yet optimized for React Native's autolinking feature. A workaround is creating a file named "react-native.config.js" in the modules root folder with the following content:

module.exports = {
  dependency: {  
    platforms: {  
      android: {  
        packageImportPath: 'import fr.michaelvilleneuve.customcrop.RNCustomCropPackage;',  
        packageInstance: 'new RNCustomCropPackage()',  
      },  
    },  
  },  
};

      },  
    },  
  },  
};  

Did that and the bad import was still being generated in Package.list. Do I need to do something else in order to make it work?. Seems like my react-native-config is being ignored.

EDIT: Made it work, I had a typo and wrote react-native-config.js instead of react-native.config.js

@syedsadiqali Did you solve this error ?
@JaimePata this solution not working ...

Same issue here, not sure how to fix it

[JaimePata]

@shahzaibali-code the solution worked for me, but is far from ideal.
The react-native-config file that you should edit is the one from react-native-perspective-image-cropper, inside your node modules.
So everytime you install the module you should change that file.

[syedsadiqali]

@shahzaibali-code sorry I'm not working on react native for a long time.

[r0b0t3d]

@JaimePata there is 2 ways you can overcome that issue.

1. Try to make a fork of this repo then add react-native.config.js and use it instead. If you can make a PR, it will be great.
2. Use patch-package.

Currently, I used the option 2 because I have to modify the source code to fit my need.

Still facing the issue.

Hi,
Your solution is worked for me. Thank you.
Note: I am not using this package. I integrated opencv to develop with c++ in my React Native project. But it was giving this error. This answer fixed the problem. Thanks again 🙌
